[Practical approach to recurrent benign paroxysmal positional vertigo].
Benign paroxysmal positional vertigo is the most common vestibular disorder and it has a significant impact on health-related quality of life. The disease is probably caused by the accumulation of lithiasis material from the otolithic membrane of the utricle. Patients experience multiple short vertigo crises lasting seconds when they go to bed or turn over. There are several clinical variants affecting posterior, horizontal or anterior canals and in some cases vestibular lithiasis can occur in two canals simultaneously. Diagnosis is by video-oculographic recording of positional nystagmus during positional tests to identify the canal affected. There are specific treatment manoeuvres for each clinical variant, which a high degree of short-term effectiveness.
